It’s not just about people who stand on the right hand side of escalators. There seem to be lots of pedestrians who, in high-traffic areas, manage to block things up and slow people down. Some — and it’s not just oldsters and tourists — will walk slowly in the middle of a path that fits two. Some groups of people will walk slowly in parallel, contracting when others pass in the opposite direction, but filling the space instantly afterwards, so nobody else can pass.
I know, I know, I should allow more time to get where I’m going. But inevitably sometimes I’m in a hurry — as seen by Jen last night. While no footpaths have formal slow and fast lanes, I for one would appreciate if those walking slowly kept to one side to let the speedsters through.
